Beef and Pepper Cheesesteak Sandwiches

Ingredients

• 600 g beef sirloin or rump steak
• 1 tablespoon neutral oil, divided
• 2 onions, thinly sliced
• 1 large green pepper, thinly sliced
• 1/2 teaspoon fine salt, divided
• 1/4 teaspoon black pepper
• 1/2 teaspoon garlic powder
• 160 g sliced provolone or mild melting cheese
• 4 sturdy sandwich rolls, about 18 cm long
• 2 tablespoons water for melting the cheese

Instructions

1. Slice with care. Pat steak dry and slice as thinly as practical across the grain with a sharp knife. If soft, firm it in the freezer for 15–20 minutes first without freezing solid, allowing that extra time in your plan. Separate the slices so they cook evenly. Clean the raw-meat board before preparing bread or cooked food.
2. Brown the vegetables. Heat 2 teaspoons oil in a large skillet over medium heat. Cook onion and pepper with a pinch of the salt for 10–12 minutes until soft and browned at the edges, stirring occasionally. If they catch before softening, add a tablespoon water. Transfer to a bowl.
3. Cook beef in small batches. Raise heat to medium-high and add the remaining oil. Cook beef in two or three loose batches rather than one thick pile, turning until just cooked and lightly browned. Season with remaining salt to taste, pepper and garlic powder. For whole-cut beef, reach at least 63°C/145°F and rest for at least 3 minutes; for very thin slices, checking a small stack helps position the thermometer.
4. Warm the rolls. Split the rolls lengthways while leaving a hinge along one side. Toast the cut faces in a clean pan or under the grill until lightly crisp, watching closely. A thin crust on the inside helps the bread hold up to the hot filling without making the outside difficult to bite.
5. Combine and melt. Return the cooked vegetables and beef to the skillet over low heat. Divide into four rough portions and top with cheese. Add the 2 tablespoons water at an empty edge of the pan and cover for about 1 minute, just until the cheese melts. Avoid a long simmer that toughens the thin beef.
6. Fill and serve. Lift each cheesy portion into a warm roll with a broad spatula. Press the hinge gently around the filling and serve at once. If there is liquid in the skillet, leave it behind rather than pouring it into the bread. Offer extra pepper or condiments separately.

Tips and troubleshooting

If the pan fills with liquid, cook the remaining beef in smaller batches and let the empty pan regain heat between them. Thin slicing matters more than buying an unusually expensive cut. Do not keep reheating all the beef while waiting for the bread; prepare the rolls before the final cheese stage.

Substitutions

Sliced mushrooms can replace some of the pepper or onion if cooked until their water evaporates. Use Emmental or mozzarella when provolone is unavailable. For a lighter portion, use smaller rolls and save some filling separately rather than overstuffing.

Allergen notes

Contains milk and wheat. Rolls may contain sesame, egg or soy; check the bread and cheese labels for your requirements.

Storage and reheating

Refrigerate cooked leftovers in shallow covered containers within 2 hours, or within 1 hour above 32°C/90°F. Keep the refrigerator at 4°C/40°F or colder and use cooked leftovers within 3–4 days. Reheat cooked fillings thoroughly to 74°C/165°F. Store salad and cold sauces separately; reheat only the portion needed. Discard food left out beyond these limits. Assemble fresh bread or tortillas only after reheating the filling; stored assembled sandwiches and tacos become soggy.
